If m<7 is 2x + 30 and m<28 is 3x - 10, find the following:

topjm [15]

Answer:

x = 32

m∠7 = 94

m∠8 = 86

m∠3 = 94

Step-by-step explanation:

(2x + 30) + (3x - 10) = 180

5x + 20 = 180

5x = 160

x = 32

m∠7 = 2(32) + 30 = 94

m∠8 = 3(32) - 10 = 86

or

m∠8 = 180 - 94 = 86

m∠3 ≈ m∠7 (corresponding angles)

Two trains leave stations 306 miles apart at the same time traveling toward each other one is traveling at 90 mph the other at 8

Sergeu [11.5K]

Answer:

They will meet in 1.8 hours.

Step-by-step explanation:

Given that, distance between trains = 306 miles

Let they take time $'t'$ to meet each other.

Speed of first train = 90 mph

Speed of second train = 80 mph

Let distance traveled by first train = $D_1$ miles

Formula for distance:

$Distance = Speed \times Time$

Distance traveled by first train, $D_1 = 90t$

Let distance traveled by first train = $D_2$ miles

Formula for distance:

$Distance = Speed \times Time$

Distance traveled by first train, $D_2 = 80t$

Total distance traveled is 306 miles.

i.e.

$D_1+D_2=306\\\Rightarrow 90t +80t=306\\\Rightarrow 170t=306\\\Rightarrow t =\dfrac{306}{170}\\\Rightarrow \bold{t=1.8\ hr}$

They will meet in 1.8 hours.
